HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 714,985, dated December 2, 1902.

Application filed February 19; 1902. Serial No. 94,830. (No model.)

To all whont it nmy concern.-

Be it known that I, J AMES M. WIsHAR'r, a citizen of the United States, residing at Pasadena, in the county of Los Angeles, State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to a burner designed to burn the light grades of crude petroleum, kerosene,and distillate from crude petroleum and the objects thereof are to produce a burner which will burn such fuel with a minimum amount of smoke and which is of simple construction and easily operated. I accomplish these objects by the burner described herein and illustrated in the accompanying drawings, forming a part hereof, in which- Figure 1 shows my burnerapplied toa fragment of a cooking-stove, the front being re moved for clearness of illustration and the other parts being omitted as not necessary to the illustration of my invention. Fig. 2 is a plan View of my burner removed from the stove. Fig. 3 is a perspective view of the spreader 4.- 4 of Fig. 2.

In the drawings, A is the stove, and B is the fire-box thereof, in which my burner is placed.

My burner is constructed as follows:

C is the bed-plate, which extends from end to end and from side to side of the fire-box and preferably rests on the supporting-lugs D of the stove, which are provided to support the grate; but any other means may be adopted to hold it in its proper position in the fire-box. This bed-plate is provided with the circularflame-port E, preferably centrally disposed therein, the walls of which project above the bed-plate, (shown most clearly in Fig. 4,) and the starting-port F preferably at one edge thereof. On the bottom of the bedplate is slidably mounted damper G, which is adapted to close the flame-port when the starting-port is fully open and to close the starting-port when the flame-port is fully open. This damper is provided with an operatingrod H to change its position, and thereby open and close the respective ports. Affixed to the bottom of the bed-plate by bars I or to the delivery-pipe, preferably below the Fig. 4 is a cross-section on the line fuel-port, is the fuel-holding starting-cup J, which holds the necessary quantity of liquid fuel required for heating the retort K to vaporize the liquid fuel. The retort is affixed to the upper side of and at one edge of the bedplate and above the starting-port projects upward and slightly toward the center of the bed-plate. It is preferably a thin rectangular cast-iron box, to which is connected, preferably at the upper edge and at one end, the liquid-fuel-supply pipe L, having cock M thereon to control the supply of fuel. At the other end and opposite the supply-pipe is the delivery pipe N, which runs down through the bed-plate and thence to below the flame-port, where it terminates in an upturned end, which constitutes a tip 0, having eduction-port P therein. Resting upon the upper surface of the bed-plate, so that the top thereof may be disposed above the flame-port,

is the spreader R, which spreads the flame.

Ihave illustrated and described my burner as applied to a cooking-stove, but it is applicable to heating-stoves, furnaces, and other like structures.

My device being in position in a stove and connected with a suitable fuel-supply, cock M is opened and the liquid fuel is permitted to nearly fill the starting-cup, when the cock is closed. The damper is moved to close the flame-port and open the starting-port, as shown in Fig. 4, and the fuel is lighted. The draft will cause the flame to enter the start ing-port and pass upward into contact with the retort, which it will heat sufficiently hot to vaporize the liquid fuel therein. The vapor is led from the retort to the flame by the delivery-pipe. As soon as the retort is sufficiently heated to produce vapor the damper is moved to close the starting-port and open the flame-port. The passage of the vapor through the flame-port and the natural draft cause air to be drawn into the fire-box and to mix with the vapor, and thereby produce an inflammable mixture, which strikes the spreader and burns with very little smoke in a broad flame. As the top of the spreader projects toward the retort, the flame is caused thereby to impinge against the retort, and thus keep it at a temperature which will cause the vaporization of the liquid fuel which enters therein.

In the drawings I have illustrated my burner with the retort placed at the front of the firebox, because I have found in practice that it works very well in that position. It may be placed at the back of the fire-box, if desired, or elsewhere therein; but in whatever position it is placed it must be so located that the flame will impinge it when in use.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ahydrocarbon-burnercomprisingabedplate having a flame and a starting port therein; a damper affixed to said bed-plate adapted to control'said ports; means to move said damper; a slightly-inclined upwardlyextending retort disposed above the bed-plate, inclining from above the starting-port toward the vertical plane which passes longitudinally through the center of said bed-plate; a fuelsupply pipe connected with said retort at one end; a delivery-pipe connected to the other end of said retort at the top thereof and running thence to and terminating below the flame-port and having an ed uction-port therein below the center of the flame-port, adapted to discharge vapor into said flame-port.

2. Ahydrocarbon-burnercomprisingabedplate having a flame-port centrally disposed therein, the walls of said flame-port projecting upwardly therefrom, said bed-plate also having a starting-port at one side thereof; a

damper slidably mounted to said bed-plate, adapted to control said flame and starting ports; an upwardly-extending retort disposed above the starting-port of the bed-plate; a fuel-supply pipe connected to said retort; a delivery-pipe connected to said retort at the top thereof and running to below the flameport and having an eduction-port therein disposed below the center of the flame port adapted to discharge vapor therein; and a spreader disposed above said flame-port.

3. A hydrocarbon-burner comprising a retort affixed to a bed-plate above and at the edge thereof, a starting-portin said bed-plate below the retort; a flame-port centrally disposed in said bed-plate; a spreader disposed above said flame-port; a damper adapted to alternately open, and close said starting and flame ports; a fuel-supply pipe connected to said retort; a delivery-pipe connected to said retort at the top thereof and extending to below the flame-port and having an eductionport therein disposed below the center of the flame-port and a starting-cup disposed below said bed-plate.

In witness that I claim the foregoing I have hereunto subscribed my name this 11th day of February, 1902.
